It's funny to hear these all from prj. Practically nobody can tune Aisin TCUs. And this man has their clients. Not only from Volvo because these transmissions were installed on many different cars. Alpha, French, Japanesse and etc.

About Volvo engines. Many 30+ mans like Volvo and don't like Audi. Prj suggests to changes their cars from Volvo to Audi 3.0TDI to go faster? Are you seriously? In such case you can just buy Tesla Plaid and forget about everything. I really regret that I bought my first Volvo 12 years ago. Was better stay on Russian cars. But what was done was done.

bro, did someone hack your account?
speaking of secrets
could you write me some asm for a flex fuel sensor? )))

I would love to find pointers on how to read and tune the Aisin in one of my Volvos. Is the VAG stuff related at all and can I find something there that I can use on my Volvo?

Let's all be nice to each other (or at the very least not hostile) and leave the whole value and secret stuff discussion off this topic. The whole market in aftermarket tuning is filled with people wanting to make money, some actually do. Very few of the ones making money respond here, most read and learn and keep their mouth shut. None of them here will tell here how much time and money they invested and how much money they made eventually, so the discussion in my opinion is pointless and takes away from the good stuff happening here.

Have you ever drive any modern car that does 4s 0-100stock?
If you did you probably noticed that it reach this "magic" 100 so quick that it starts to become irrelevant to performance.
You just "jump" into 100 and THEN actual performance starts to matter.
And this is what old Volvos or any aold tuned car can also do very well and compete with the fastest and most modern cars!
Because what metters up to around 100 (or even less, like 60) is mostly drivetrain, not engine.
I was driving 300HP BMW M135ix and 420HP A45S AMG (2022+ production) and on paper one is doing around 4s other around 4,8s (or whatever) but in reality they reach this 100 practically the same. They both do this so well that 120HP gap just doesnt matter at so low speeds. All that matters is drive train. BUT after 100km/h real performance starts to bee visible. And 135i is just slow AF compared to A45S.

My point is that all those 0-100 wars had any meaning many years ago when 7s or 8s was considered fast and when you cut 1s it was really impressive.

Modern "races" are from 100 up-wards. 0-100 are more or less the same in modern faster cars from practical point of view.
Car technology reached grip limit already at lower speeds. There is nothing more to improve. But at higher speeds, engine power is as always most important factor.

So tuning older cars with "classic", not efficient drivetrain have still a lot of sense this day, you can "destroy" modern cars above 100 when what matters is pure engine power.

My daily driver for the past 7 years has been a car that does 3.3s 0-100 with stock hardware and just a remap. I don't know how "modern" it is, it's now 12 years old.
Not in most civilized countries. Do some 0-100 in the city and most likely you end up without a license.

Let me put it this way, my stock car does around the same 100-200 that some of the 0-100 posted here, but does not matter.

Really now? I don't know where you're doing that shit.
Drag race starts at 0. Lights start at 0. It's like creating a new special (retarded) discipline to show off the one tiny thing you can do decently. "Fastest FWD car with stock turbo, stock intercooler and modified exhaust in the world" or some other stupid highly specific stuff like that.

Grip limit on decent powertrain 0-100 is over 1000hp, not the things you say here. I don't have any issues with grip after 20-30km/h and I have just 650hp.
Maybe if you run dogshit tyres on tiny pizza cutter wheels it's a problem...

Anyway, does not matter.
As BaxtR said very well:

Having "secrets" on 20 year old shit is completely retarded. It's like being proud of wagging your dick around at a micropenis competition.
Cooperation is much more important, because in the end it's a tiny enthusiast community with these old cars - there is no significant money to be made here.
Already 10 years ago when I was tuning these cars there was super low demand for it, because usually the people who buy a Volvo are those that don't care about any tuning. And here are a lot of Volvos on the streets.

I think P3 and some late P1 there is probably some money to be made, but P2 is completely dead from that standpoint.

Your P1 C30 is probably ME9?
In that case my logger supports it and there's a Ford ME9 damos floating around that you can use as a base for locating the maps, it's extremely similar.
The control logic does not differ much from ME7.

I know that very well. My logger supports both D2 and UDS.
I bought both types of ECU

The protocol detects this automatically.

For the money you spent tuning you can buy a new engine for the V6 if you wanted to, besides the camshaft tensioners on the Volvos aren't exactly cheap or maintenance free. Also, if you don't like the V6, BMW has an inline 6...
My point is simply - spending a long time and having some "secrets" on a platform that came out over 25 years ago today is a complete waste of time. Especially when half the family cars on the road are faster than your tuned car with your uber secrets.

Pretending that 25 year old platform is somehow worth keeping any secrets on is completely insane.
